-IMPROVEMENT IN WAGON-BRAKES.

Specification forming part of Letters Patent No.*l73,975, January 22,1876.

t To all `whom it may concern:

-being had to the accompanying drawings, and

to the letters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists in the construction and arrangementof a lock-lever for wagon-brakes, as will be hereinafter more fully setforth.

In order to enable others skilled in the art y to which my inventionappertains to make and use the "same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure l` is a perspective view of my invention. Fig. 2 is a section ofthe lever.

A represents the arch, formed with a series of inclined notches, a a, onits inner side, and a barrel or tube, B, at each end, which projectsinward, and through which the bolt b passes.l for fastening the arch tothe side of1 the wagon-body. From the inner end of one of the barrels ortubes B projects a side strap, O,to

a'point at or near the center of the arch.

The arch A, barrels B B, and side strap C are all to be made in onepiece, of malleable, wrought, or cast iron.

Dis the handle or lever, made of malleable,

dated February 22, 1876; application filed wrought, or cast iron,pivoted at its lower end to the wagon-box by a bolt, d, passing, also,through the end of the side strap C, andthe lever or handle extending upbetween the wagon-box andthe arch. The lever D is provided ywith atooth, shoulder, or oset, c, to enter either ofthe notches a of the archA, into which it is held by a iii-at spring, G, secured on the outsideof the lever by the bolt y d, and extending'up on the ouside of thearch,

as shown. The tension of this spring is regu lated by means of a bolt,h, and nut i, the bolt passing through the springand the lever. At thepoint where this bolt passes through the lever a slot, m, is made in thelever, for the reception of the connecting-rod, which is pivoted in saidslot by the same bolt h.

The end of the spring Gr, where it Works against the arch, is to beplated with steel or 4 iron, to prevent it from wearing out. Having thusfully described my invention, what I claim as,new, and desire to secureby Letters Patent, is-

The combination, with the arch A, lever D, and spring G, of thetension-regulating bolt h and nut t, for the purposes herein set forth.

In testimony that 1 clailn the foregoing I have hereunto set rmy handthis 6th day of January, 1876.
